Before we unveil our list of the Islanders’ top prospects not currently with the big club or playing in Bridgeport, a few notes:

– The list was compiled with our knowledge of the prospects combined with the views of three NHL amateur scouts.

– The key word is here “upside.” It is very possible some lower-ranked players could make the NHL while some of the more highly-ranked never get here. This list is of the players with the most potential.

– No, we did not forget anyone (Blake Kessel, Jason Gregoire, David Toews, Jyri Niemi, Justin DiBenedetto). There is still plenty of time to move up the chart for our next ranking.

– That said, based on need and timing – and ability, naturally – it’s possible the Islanders could sign a player or two not on this list before they sign a player on it.

Here goes.

10. LW DAVID ULLSTROM, 19 years old

Drafted: 4th round, 2008

Now Playing: Boras HC, Swedish Elite League

NHL Upside: Second or third-line forward with high-end skill and speed

Scout: “A real sleeper. Great value in the fourth round.”

9. G STEFAN RIDDERWALL, 20 years old

Drafted: 6th round, 2006

Now Playing: Djurgardens, Swedish Elite League

NHL Upside: No. 2 goalie with an outside chance of pushing for No. 1

Scout: “If he wants to be in the NHL, he should come over in a year or two and start in the American League. Definitely has the talent.”

8. LW MATT MARTIN, 19 years old

Drafted: 5th round, 2008

Now Playing: Sarnia, Ontario Hockey League

NHL Upside: Leadership, character, toughness

Scout: “Keeps on getting better. Probably not much more than a third-line player, maybe fourth line, but I think he’s a winner. Every team wants a kid like this.”

7. D MARK KATIC, 19 years old

Drafted: 3rd round, 2007

Now Playing: Sarnia, Ontario Hockey League

NHL Upside: No. 3-4 defenseman

Scout: “Still has to show more. The skills are there. I think the Islanders will sign him and I think he’ll play, but he has to show more consistency to make it as a top-4.”

6. D TRAVIS HAMONIC, 18 years old

Drafted: 2nd round, 2008

Now Playing: Moose Jaw, Western Hockey League

NHL Upside: No. 2-3 shutdown defenseman

Scout: “Solid. Could he be special? I don’t know. Just a real good stay-at-home defenseman who should have a long career.”

5. RW RHETT RAKHSHANI, 20 years old

Drafted: 4th round, 2006

Now Playing: University of Denver

NHL Upside: competitive and skilled second-line right wing

Scout: “Skating is not great, but makes up for it with playmaking ability and work ethic.”

4. LW ROBIN FIGREN, 20 years old

Drafted: 3rd round, 2006

Now Playing: Djurgardens, Swedish Elite League

NHL Upside: same as Rakhshani, but on the left side

Scout: “Should be an excellent fit in Scott Gordon’s system when he returns from Sweden. A very good all-around player with intangibles.”

3. C COREY TRIVINO, 18 years old

Drafted: 2nd round, 2008

Now Playing: Boston University

NHL Upside: same as Figren and Rakhshani, but down the middle and with blazing speed

Scout: “Kid can fly. If he can put it all together…”

2. D AARON NESS, 18 years old

Drafted: 2nd round, 2008

Now Playing: University of Minnesota

NHL Upside: No. 2, Rafalski-like defenseman

Scout: “Only went in the second round because of size (5-10, 160). The Islanders may have lucked into this one.”

1. RW KIRILL PETROV, 18 years old

Drafted: 3rd round, 2008

Now Playing: Kazan Ak Bars, Kontinental Hockey League

NHL Upside: First-line wing

Scout: “The ultimate wild card. Don’t know when he’ll come over. Probably won’t be for another year or two at the earliest. But for a team with all those early round picks, the Islanders were smart to grab him. Too much skill to ignore.”
